PREDICTING DISINFECTION BY-PRODUCT FORMATION: A Comparison of Photoelectrochemical Oxygen Demand to Traditional Source Monitoring Parameters

摘要

Preventing the formation of DBPs is a multi-faceted challenge for drinking water utilities, with a variety of strategies being developed for both general treatment and specific plant/source conditions. Each facility and water source are different, therefore no one strategy can be applied across the board, and often utilities are encouraged by their local authority to have a unique monitoring plan developed. Prevention strategies can be generalized into four groups:1. Optimization of treatment conditions to remove precursor NOM compounds;2. Using a different chemical disinfectant with less tendency to form by-products;3. Using a non-chemical disinfectant; and/or4. Removing DBPs prior to distribution.
